FRANK E. WELLMAN, OF KANSAS CITY, KANSAS, ASSIGNOR TO THE KANSAS CITY GASOLINE COMPANY, OF KANSAS CITY, KANSAS, A CORPORATION OF KANSAS.

FUEL-FEEDING- SYSTEM.

Specification of Letters Patent.

Patented Jan. 28, 1919.

To all whom it may concern:

Be it known that I, FRANK E. WELLMAN, a citizen of the United States, residing at KansasCity, county of Wyandotte, State of Kansas, have invented certain new and useful Improvements in Fuel-Feeding Systems, of which the following isa specification, reference being had therein to the accompanying drawing.

My invention relates to furnaces using liquid or gaseous fuel and has for its object an apparatus for the control of the combustion in the said furnace at a safe distance therefrom.

I attain my object by devising means for controlling the supply of fuel and air separately, and at a safe distance from the furnace, as for example, 150 feet. This is accomplished by placing the pumps or compressors for forcing the fuel and air into the combustion chamber in a control house at a safe distance from the furnace, and leading the fuel and air pipes from said control house to the furnace where the fuel is mingled with the air and a combustible mixture is forced into the combustion chamber.

My invention is illustrated in the accompanying drawing, oil being taken as the fuel and air as the source of oxygen.

Figure 1 is a side view of the apparatus in conventional form.

Fig. 2 is a plan view of Fig. 1.

Referring to the drawings, A is an operating house. B is an oil pump. 0 is a control valve. D is an oil pipe line constructed in the form of a U between the points 03' and d", leading from the pump B to the nozzle K, and containing the valve C. E is the oil supply pipe line. F is an air supply intake for the an compressor G. H is a control valve. I is an air pipe line between the compressor G and the nozzle K and containing the valve H. K is a mixi g nozzle in which the oil and air are in 1- mately mixed, and from which this combustible mixture is expelled into the combustion chamber of the furnace. L is the combustion chamber.

The method of operation of this apparatus is as follows: 7

The pum B receives its supply of oil from pipe and forces it in a continuous stream through pipe D and the control valve 0. The supply of oil to the furnace is controlled by the hand operated valve C. In order that oil may be supplied immediately to the furnace upon starting up, the pipe D is shaped somewhat in the form of a U so that the lon section of the pipe between the points and d" does not drain and remains always full of oil. Thus the oil starts flowing into the furnace immediately upon opening the valve 0. The compressor G receives the air from its intake pipe F and forces it through the pipe I fitted with control valve H for controlling the supply of air. The oil and air from the pipes D and I respectively come together in the mixing nozzle K. Here the oil and air become intimately mixed, the oil being divided into a fine mist. This combustible mixture then exhausts into the combustion chamber in the form of a spray, and readily burns.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

In a system of the class described, a furnace, a control station situated at a safe distance from the furnace, fuel and air pipes leading from said control station to the furnace, a mixer thereat wherein the fuel and air are intimately intermingled, a valve in the fuel pipe at the control station, and means for maintaining the entire length of the fuel pipe between said valve and said mixer filled with fuel at all times.

In testimony whereof I aflix my signature.
